Research Collection School Of Computing and Information Systems

As part of its continuous process to improve operational excellence and productivity, a retail company in South East Asia trialed the usage of a commercial market retail tool, known as Queue Buster, to improve queue management processes in its physical stores. We employed Queuing Theory to determine the effectiveness of implementing the Queue Buster. Specifically, we constructed a queuing simulation model based on input parameters derived from queuing data collected at a pilot store. Three main performance metrics - Wait Time, System Time and System Length were measured fortwo different queue systems, with and without the implementation of Queue Buster. …

Urban Consolidation Center Or Peer-To-Peer Platform? The Solution To Urban Last-Mile Delivery, Qiyuan Deng, Xin Fang, Yun Fong Lim

Research Collection Lee Kong Chian School Of Business

Booming e-commerce activities further increase this demand, exerting intense pressure on the cities' well-being. To build a city with congestion and pollution under control, a consolidator can operate an urban consolidation center (UCC) to bundle shipments from multiple carriers before the last-mile delivery. Alternatively, the consolidator can operate a peer-to-peer platform for the carriers to share their delivery capacity. Our objective is to compare the performance of these two business models. Under each business model, we study the interactions between a consolidator and multiple carriers using a two-period game-theoretical model. In each period, the consolidator first chooses a delivery fee …

A Study On Spare Aircraft In Brazilian Airlines, Clarissa Pinheiro Pereira, Eduardo Sakashita, Eliudes Del Grande, Guilherme Bevilacqua

Graduate Student Works

All around the globe, the airlines struggle to sustain profitability. They are deeply affected by the region’s economy. It goes from the fuel price and exchange rate to the level of employment and average salary. That makes it imperative to control the cost, and also to balance very well the cost and level of service. Aircraft utilization is one KPI that measures productivity. Once the airline has a high aircraft utilization, it means that the resource has been productive, hence more cost-efficient.

On the other hand, flight cancelations and delays result in costs and passengers’ dissatisfaction. In Brazil, there is …

Your Community Gets A B-: Analysis Of The Specific And Curious Realm Of Airport Bond Rating, Richard W. Hawkins, Stephen A. Lemay, Peter M. Ralston

Journal of Transportation Management

Commercial airports are publicly-owned transportation infrastructure, usually funded with bonds. The bond rating decision for these entities thus has important ramifications for bond investors, issuers, airport managers, and even the communities the airports serve, but the rating decision process is not well understood. This paper discusses a simulation of the rating process in two decision environments, including a downgrade. The effect of information framing in an environment of incomplete data is examined using amateur evaluators. Amateur evaluators were utilized to understand how people with limited financial analysis skills would respond when presented with incomplete information and a primed scenario. The …

An Experimental Test Of Green Management Information System Effects On Carrier Selection: Weigh Station And Tollbooth Bypass Technology Adoption, Rodney W. Thomas, Jessica L. Robinson, Jessica L. Darby, Scott Cox, Donnie F. Williams Jr

Journal of Transportation Management

In a highly competitive price-driven industry, carriers are continuously searching for opportunities to differentiate their offerings, minimize operational costs, and appeal to shippers. At the same time, environmental sustainability has evolved from being trendy jargon into a requirement for competitive supply chain management. It is at the intersection of these two modern topics that the current study identifies a new carrier selection attribute based on a specialized type of green management information system. We apply social exchange theory to hypothesize carrier price and green technology adoption effects on shipper purchase intent. The hypothesized direct and interaction effects are tested by …

Social Media And Supply Chain Risk Management: Improving Risk Detection And Supply Chain Resilience, Scott R. Cox, J Kirk Atkinson

Journal of Transportation Management

The introduction of social media has changed the methods by which many individuals, communities, and organizations communicate and interact. The increasing popularity of social media within a business context has forced executives to rethink how they operate their businesses. Chae (2015) observed that the field of supply chain management (SCM) has been lagging in identifying the potential role and use of social media in both research and practice. Recently, greater attention is being given to social media and its potential uses within the supply chain. This paper investigates the potential use for social media as a technology to help with …

The Tumultuous World Of Global Maritime Transportation: A Cautionary Tale For Supply Chain Managers, Kent N. Gourdin

Journal of Transportation Management

The past five years have seen unprecedented changes transform the way goods are moved around the world. The expanded Panama Canal now permits larger vessels as well as simultaneous transits in each direction. Coincidently, steamship lines began purchasing a new generation of bigger ships, forcing ports in the United States to make very large investments in new infrastructure. When examined within the context of other environmental events impacting global trade, the total effect has been to put the maritime industry into a state of flux. This paper will examine these and other important issues before offering conclusions intended to help …

B-Line Sustainable Urban Delivery: Can Last-Mile Bicycle Delivery Survive The E-Commerce Minefield?, Madeleine Pullman, Jacen Greene, Wanying Shi, Stephan Kaplan

Business Faculty Publications and Presentations

As the population of cities in the western United States continues to boom, the demand for retail and wholesale food has followed suit. To deal with the accompanying increase in traffic and congestion from population and business growth, the city of Portland planned to increase bikeways and reduce the use of single-occupant vehicles to less than 30% of total commuters by 2026. Despite efforts to decrease dependence on vehicles, traffic congestion in Portland
continued to increase, and traditional vehicle delivery in the urban area became less and less efficient. As ride-sharing services and online retailers increased their presence in the …

Perceived Fit Between Green Is And Green Scm: Does It Matter?, Zhaojun Yang, Jun Sun, Yali Zhang, Yin Wang

Information Systems Faculty Publications

From a task-technology fit perspective, green SCM and green IS are likely to have synergistic effects on corporate sustainability. Yet, the exact mechanisms through which their perceived alignment by employees may exert influences on organizational performances are unclear. This study captures potential enablement and coverage routes at different development stages of sustainability with fit-as-mediation and fit-as-moderation, respectively. The results based on the observations collected from more than 400 organizations in the USA and China suggest that the perceived fit gradually shifts from a moderator role to a mediator role as the two green endeavors integrate with each other.

Data-Driven Predictive Maintenance Scheduling Policies For Railways, Pedro Cesar Lopes Gerum, Ayca Altay, Melike Baykal-Gürsoy

Supply Chain Management

Inspection and maintenance activities are essential to preserving safety and cost-effectiveness in railways. However, the stochastic nature of railway defect occurrence is usually ignored in literature; instead, defect stochasticity is considered independently of maintenance scheduling. This study presents a new approach to predict rail and geometry defects that relies on easy-to-obtain data and integrates prediction with inspection and maintenance scheduling activities. In the proposed approach, a novel use of risk-averse and hybrid prediction methodology controls the underestimation of defects. Then, a discounted Markov decision process model utilizes these predictions to determine optimal inspection and maintenance scheduling policies. Furthermore, in the …

How To Optimize Storage Classes In A Unit-Load Warehouse, Marcus Ang, Yun Fong Lim

Research Collection Lee Kong Chian School Of Business

We study a problem of optimizing storage classes in a unit-load warehouse such that the total travel cost is minimized. This is crucial to the operational efficiency of unit-load warehouses, which constitute a crit- ical part of a supply chain. We propose a novel approach called the FB method to solve the problem. The FB method is suitable for general receiving-dock and shipping-dock locations that may not coincide. The FB method first ranks the locations according to the frequencies that they are visited, which are estimated by a linear program based on the warehouse’s layout as well as the products’ …
